Your ISPs DHCP does not function properly

hi @ComcastChe 

i see that you have helped other uses in the past. I tried calling and the rep wasnt helpful really at all. I recently upgraded my modem and everything was working fine until the power outage. When power came back, the moden connected just fine, so all my hardwired devices are good. 

But my Asus router, i can see the WIFI signal, but it says "Internet may not be available". If i go into the router settings, it says "Your ISPs DHCP does not function properly". Nothing has changed with setup or equipment since the power went out.

Please help. Much appreciated!!
